Important changes are coming to Google Fi soon
While the option to use both features is not yet available, Google announced that Fi will soon support separate Google Voice and Google Fi numbers on the same Google account. In that regard, the Mountain View company revealed that it has decided to change the location where voicemails are stored.
Starting this week, voicemails received on Fi will no longer be available from voice.google.com. Instead, Google announced that all voicemails received will remain “everywhere else you're used to accessing them, such as the Phone app or other dialer apps on Android, or the Fi app on iOS.”
It means that Google Fi customers will now be able to access voicemail by calling their own number. Keep in mind though that all voicemails received before joining Google Fi are still accessible from voice.google.com.
Apart from changing location, Google didn't make any other changes to voicemail transcription on the Phone app on Android or Fi app on iOS, neither to the way customers use voicemail on Hangouts.
